2002- link performance optimization (subject to harsh propagation conditions) Amazonia: 220 km 2GHz low capacity Radio hop (20 Mbits/s) QoS recovery from 95% to 99.9% Availability 2006- SDH Ring design and optimization (subject to nodal interferences) Algeria: 16x STM-1 (metro ring) same set of RF channels used on all branches QoS in-line with the predictions : 99.999%2008- long distance inter-island SDH BB [7+1] Greece (Crète to Peloponese) challenging case: 3 existing BB with degraded performances QoS in-line with the predictions : 99.999% 2017: transformation to Ethernet Packet transport successfully done 2012- 230km single Radio Hop 4xSTM-1 64QAM (TXpwr per Transceiver: 1 W) Equatorial Guinea QoS in-line with the predictions : 99.999%2014- 220km 5xSTM-1 64QAM (TXpwr per Transceiver: 1 W) additional link for additional capacity2015- 185 km singe Radio hop inter-island N-LOS path (according to ITU P.530 paradigm) 160 Mbit/s Ethernet packet transport with standard power ODU (25 dBm) QoS in-line with specific prediction models : 99.999%2017- 600 Mbit/s Ethernet packet transport achieved by swap from standard to high power ODU2018 high capacity BB implementation in the Artic region 500km BB sction with multichannel packet radio challenging case: ITU P.530 method not relevant (heavy atmopsheric mutipath fading)
